HARNESS-MAKERS STITCHING-HORSE.

SPECIFICATION forming part of Letters Patent No. 225,604, dated March16, 1880.

Application filed October 11, 1879.

T 0 all whom it may concern.-

Be it known that 1, CHARLES A. HOLLAND, of Fayetteville, in the countyof Cumberland and State of North Carolina, have invented certain new anduseful Improvements in Harness-Makers Stitching-Horses; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of myharness makers stitching-horse. Fig. 2 is a plan view of the same. Fig.3 is a front view. Figs. 4, 5, and 6 are detail views, and Figs. 7 and 8are views of modifications.

The nature of this invention relates to harmess-makers stitching-horses.

My improvement consists in the construction and arrangement of parts, aswill be fully set forth in the following description, and particularlypointed out in the claims.

In the drawings, A designates theoperating-lever, composed of two barsbolted together. The foot-rest is set at the required angle by adjustingone of the bolts or screws in holes formed in one of the bars, as shown.The lever A connects with an arm upon shaft B by means of atoggle-joint, and the shaft B is provided with a spring which throwsback the operative mechanism of the machine after a forward stroke ofthe same. a I

G designates a pivoted lever-bar, which is mounted upon a slide, D, andoperated by a crank-arm upon the shaft B. This lever-bar carries thetack-extractor E in rear of the slide 1), and is arranged so as tooperate the needle F. I

The needle-carrier G and the slide D are either formed in one piece orunited together, so as to have during operation a simultaneous movement.

The tack-extractor, which is designed to extract tacks from the strapsbefore they are fed between the j aws of thevise, is composed of twoplates secured to the sides of the lever G, and curled inward at theirlower edges, so as to catch under the heads of the tacks and withdrawthe same from the leather as the rear end of the lever is elevated bythe crank-arm of the shaft B.

H designates the feed device, which is formed with a lug or projection,h, which is arranged to work in a slot, I, formed in the slide D. Thefeed device H, which is serrated upon its under side, approximates inform to two wedges, having a taper from its forward end to the lug h,and also a taper from the lug to its rear extremity, there being, asshown, an increased thickness at the central part, where the lug islocated.

K designates a set-screw arranged to pass through the short standard ofthe slide, upon which the lever (l is pivoted. As the slide and carrierare thrown forward this set-screw strikes against the lug h, and henceit is made adjustable, so as to determine the movement.

of the feed. v

L represents a spring, which is secured to one of the clamping-j aws ofthe vise, and which engages with lug It so as to control the feed.

M N designate the two hinged jaws of the vise, and O a board in which aplate to which these jaws are hinged is secured. Both of these jaws arerecessed, and each jaw carries a spring. As herein shown the spring inthe jaw M is considerably shorter than the one in the remaining jaw.

P designates a pin, which is secured to the spring (1 in jaw M by nuts;and Q, a block secured to the inner face of jaw N and formed with'ahole, through which the pin is arranged to pass when the jaws arebrought together. After the jaws are thus closed a screw, R, is passedthrough the jaw N and its long spring and screwed into the end of thepin P, thereby holding the jaws together. In this way springjaws areattained which will open sufficiently to allow of the free passage ofthe straps or traces which are being sewed, and which will readily yieldto any crimps in the leather.

By means of the nuts which secure the short spring upon the pin thespring. force may be regulated to suit the work to be done.

S designates a thumb screw arranged to work in the block Q, and adaptedto open the jaws, being provided with a pin, T, which, when thethumb-screw is turned in one direction, bears against the jaw M, andhence opens the two jaws. When turned in the other direction the jawswill automatically close together.

U U designate bars, which are secured to the jaw M, and these bars areformed with bearings for the shaft B.

V represents an an gular-shaped bar carrying the guide and frictionrollers V V, and W a guide, which, like the bar V, which carries therollers, is made adjustable. For this purpose the roller-bar V and thebar which carries the guide are slotted, and both connected to one ofthe barsU by a thumb-screw. At each forward stroke of the lever a traceor straps to be sewed will be fed forward between the jaws just onestitch. When the fced reaches its forward limit the lever-bar, whichcarries the tack-extractor, and which has forced forward the carrier andslide, and consequently the feed, actuates the needle and causes thesame to pass through the leather.

.The machine is to beiastened on a bench and worked by foot, the sewingbeing done by hand through the holes made by the needle or awl.

In Figs. 7 and 8 of the drawings I have shown one of the jaws providedwith devices for so moving the strap-guides that during operation of thehereinbetore-described mechanism the strap will be punctured by the awlin a wavy line. Such devices consist of a flat bar, 1, which is pivotedupon the pin 2 at one end, and adapted at its remaining forked end toengage with a pin, 3, upon the slide which unites with the awl-carrier.

Within a recess in the jaw and below the bar 1 is a ratchetwheel, 4,which is rigidly secured upon the pin 3, and upon the under side of bar1 is a spring-pawl, arranged to engage with the said ratchet. Upon theother side of the jaw is a wheel, X, formed with a camgroove and securedupon pin 3, and in this groove works the pin 4, secured to a cross metalstrap, 5. I

In practice I propose connecting straps 5 and 6 with the bars 7 and 8,the latter of which carries the guide W. I also arrange bars 9 and 10 soas to work in guides 11, and to these I also secure the straps 5 and 6.

At each forward movement of the needle guide and carrier the movement ofthe bar 1 will cause the spring-pawl which it carries to engage with theratchet-wheel and turn the same. This also causes a movement of thewheel having a cam-groove, whereby the bars will be moved and theposition of the guide changed. A succession of such movements causes theguide for the strap to move gradually away from the jaws, and then togradually move backward toward the same, whereby the punctures in theleather will be in a wavy or serpentine line. be varied by changing adifferent cam-wheel for the one shown.

These devices are incorporated in the machine without displacing thesprings hereinbefore described, and to the intelligent mechanic thearrangement of parts to effect such result will be apparent.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a harness-makers stitching-horse, the lever A, composed of the twobars bolted together and adapted to be adjusted relatively to each otherso as to set the foot-rest at a suitable angle by means of theadjustment of one of the bolts in holes formed in one of the bars,substantially as herein set forth.

2. In combination with the sliding awl or needle carrier and feeddevice, the tack-extractor secured upon the lever which actuates theneedle-bar, substantially as shown and set forth.

3. The awl or needle carrier Gr, having a slotted slide, D, incombination with the feed device H, with lug h, the lever O, and adjustable set-screw K, substantially as set forth.

4. The feed device II, formed with lug h, and having theherein-described double wedgeshaped conformation, as shown andspecified.

5. The adjustable roller-bar V, carrying the rollers V, and theadjustable guide W, arranged as shown, and in connection with a slidingawl-carrier and feed device, as set forth.

6. In combination with thejaws and springs, the pin P and thumb-screw S,as specified.

7. Thejaws M N, one provided with a long spring and the other with aspring of less length, in combination with the pin P, secured to one ofthe springs by nuts and to the remaining spring by a screw passedthrough the jaw and spring, substantially as shown and specified.

8. The arm or bar 1, engaging with a pin upon the awl-carrier slide, thepawl on the said bar, the ratchet-wheel 4, pin 3, wheel X, withcam-groove, and the sliding bars with the strap-guide, all arranged asset forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

CHARLES A. HOLLAND.
